You cant get get cheap cams, If you want something not lumpy newman 268 be fine. Excellent cam i use 276, but very lumpy and loss of bottom end which you dont want. Kent gs2h is also excellent cam, Runs nice and not lumpy my mate uses one in his 1.9 8v. 268 newman will set you back £150, Kent about £180ish Can put you intouch with a man who sells newman cams on clubgti forum well respected as well.
